Introduction
McCormick-Deering WD-9 Standard-Tread Tractor
The McCormick-Deering WD-9 is a standard-tread tractor manufactured by International Harvester between 1940 and 1954, with the Super WD-9 series produced from 1953 to 1956. This machine was designed to serve as a high-capacity workhorse for agricultural operations during the mid-20th century.
Engine and Performance
The tractor is powered by an International Harvester liquid-cooled vertical I-head diesel engine. It features a 4-cylinder configuration with a displacement of 334.5 cubic inches (5.5 L). The engine operates at a rated speed of 1500 RPM with a compression ratio of 15.7:1. It utilizes a gasoline ignition starter system and an oil bath air cleaner to maintain operational integrity.
Transmission and Drivetrain
The power is managed through a mechanical transmission providing 5 forward gears and 1 reverse gear. The drivetrain utilizes a mechanical dry disc clutch. The WD-9 is a two-wheel drive model, designed for standard-tread applications, requiring manual steering input from the operator.
Mechanical and Dimensions
The WD-9 features an open operator station for visibility. Braking is handled by differential mechanical contracting band brakes. The machine measures 134 inches (340 cm) in length and 68 inches (172 cm) in width. Its operating weight is 6650 lbs (3016 kg), which can be increased to 10260 lbs (4653 kg) when ballasted. It is equipped with 7.50x18 front tires and 14.00x21 rear tires.
Conclusion
The McCormick-Deering WD-9 is a heavy-duty, standard-tread tractor engineered for durability and consistent performance in demanding agricultural environments. Its mechanical simplicity and substantial weight distribution make it suitable for consistent field work.
